tempmd-mcp

MCP server for temp.md — give agent-made artifacts one stable public link that updates in place.

Publish an HTML, Markdown, CSV, or Mermaid artifact and get a canonical URL like amber-hill-9eb6.temp.md. Push new versions behind the same URL — no re-sharing, ever. Temps expire intentionally when the work goes cold (7-day active window, resets on every update) and can be restored within 7 days of expiry.

Install

Claude Code

claude mcp add tempmd -- npx -y tempmd-mcp

Cursor / Windsurf / any MCP client — add to your MCP config:

{
  "mcpServers": {
    "tempmd": {
      "command": "npx",
      "args": ["-y", "tempmd-mcp"]
    }
  }
}

No account or API key required — temp.md is anonymous-create-first. Claim a Temp later to keep it.

Tools

How credentials work

publish_temp saves a record (Temp ID, URL, update token, expiry) to a .tempmd file in the project root. Every other tool reads that file automatically, so an agent can update the same Temp across sessions without you managing tokens. Tokens can also be passed explicitly via update_token.

Add .tempmd to .gitignore if the update token shouldn't be shared with everyone who can read the repo.

Configuration

Development

This repo mirrors the packages/mcp package from the temp.md monorepo, where development happens. Issues and feature requests are welcome here.

Semantics agents should preserve

• The canonical URL is the only link to share — never surface version-specific links.

• A failed update never breaks the live link; the last successful version keeps serving.

• Prefer update_temp over publish_temp when the project already has a Temp for the artifact.
